quick video of a single sided band system really manipulating the ball well, the system was actually designed to work at 90 degrees of this but i flip it on its front to prove it could go vert also.

Thanks a lot! Our team has limited prototyping resources and expertise so this really helps.

Do you know how far those rollers were from the solid plate (ie how much did you compress the ball).

Thanks again!

Wow! I didn't expect that this short video could be such assistance. Well, the plate is 8" away from the bottom of the rollers. The rollers were 2" plastic. I used solid because I plan on lathing out slots for tracks to keep the bands in line, but 2" PVC could be used in a pinch. The surgical tube were connected with a simple method I found here on chiefdelphi http://www.chiefdelphi.com/media/photos/32232 . Also, use rubber strips on the leading roller to help grab the ball. http://www.ifirobotics.com/robot-traction-wheels.shtml

Also prototypes are quite easy to build with the simplest of materials. The one in the video was made with some plastic scrap, plywood, surgical tubing (KOP), Pneumatic tubing (KOP), and a hot glue gun.

Good Luck

PS 1458build.blogspot.com there is a high quality picture of the prototype on this page
